/*
 * The ISI layout algorithm is to produce a linear time (quick) layout.
 * It does a depth first search in each direction (X, Y) placing nodes as follows:
 * - leaf nodes are placed a fixed distance from any previously layed out leaf node
 * - other nodes are layed out at the average position of their children
 *     (which causes them to sometimes overlap)
